Jonah Goldberg hopes so: 

A President Romney would be on a very short leash. … Moreover, Romney is not a man of vision. He is a man of duty and purpose. He was told to “fix” health care in ways Massachusetts would like. He was told to fix the 2002 Olympics. He was told to create Bain Capital. He did it all. The man does his assignments.

Larison finds this expectation ridiculous: 

I’m sure this is what conservative Romney supporters have to tell themselves every day, but why must he do any of this? Because he said he would? Given Romney’s special relationship with both truth and consistent political principles, I wouldn’t bet on it. … If the nomination contest has shown anything, it is that the more conservative voters have been trying to stop Romney for months and failing. Romney will see that the people identifying as the most conservative elements of the party did their best to thwart his nomination and couldn’t, so why is he going to feel obliged to them?
